To all whom it may concern.-

Be it. known that 1, DAVID Fem BROD- ERICK, of New Britain, in the county of Hartford and State of Connecticut, have in- 5 vented certain new and useful Improvements in Machines for Scourin and SCIlLtC/lr Brushing Knobs and other lletal Articles; and I do hereby declare the following to he a full, clear, and exact descri tion of the invertion, such as will enable ot ers skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in machines for securing and scratch brushing knobs, and other metal articles, and it consists broadly in a carrier adapted to convey the knobs or other articles successively to scouring brushes, and means for rotating the knobs or other articles on their supports while they are being acted upon by the brushes. I

My invention further consists in the parts and combinations of'parts as will be more fully explained and pointed out in the claims.

In the accompanying drawings, Figure 1 is a viewin transverse vertical section of my improved machine, Fig. 2 is a plan View of the same, and Fig. 3 is an enlarged view in section showing the brush, knob support and nieansfor rotating the knobs 1 represents a receptacle of any approved shape, but preferably semi spherical as shown, mounted on legs or supports 2. Passing centrally through the bottom oi rcceptacle'l is the overflow pipe 3 which latter terminates a distance above the bottom oi the receptacle, thus forming a sediment chamber into which the pumice stone or other abrading material settles, while the surplus water passes oil through the pipe 3.

4 is a ring located within and near the top of receptacle 1, and provided with inwardly projecting arms 5, terminating at'thc center m a stop bearing 6. The hearing has a bushing 7 which latter forms :t'seat for the antifrictioir bearing 8. Resting on too antid'riction or roller bearing 8 is the rotating table 9, the hub oi which has a doperulin lip 10 forming a shield or cover for the rol or hearing, and protecting the latter nu the abrading material used in hurnishi s will be hereinafter explained. Pass r c centrally through the table 9 and bushing and seis the shaft 1 i, which in orm and were: o

l K- our same 1 so proviced wit-l and romo a series of openings 28 located just above the lower brush, so that the material or fluid discharged from said shaft, comes into direct and intimate contact with both brushes 22 and 23.

Shaft 19 is driven by the belt 29 which passes around pulley 20 thereon, and under pulleys and 31 carried and up to a suitable source of power. Bolts 33 which secure block 32 in place between bars 14, pass through elongated slots-34 in said bars, thus permittin eral adjustment of the pu leys 30 and 31 to take up all slack due to the adjustment of block 16 as previously explained.

Located within receptacle 1, at a point above the table, and in a position to engage the knobs or other articles while the latter are in contact with the brushes, is the friction shoe 35 preferably made of rubber. This shoe is in the arc of a circle, preferably concentric with the path of movement of the pins 12, so as to engage the articles on said pins whereby when said knobs or articles are engaged by the shoe, the friction of the shoe t ereagainst will cause the knobs or articles which are being carried under the brushes, to rotate or turn on their pins 12, and thus bring all parts of the outer face of the knob or article and its shank into osition to be acted upon by the rapidly revo ving brushes. The rear edge of this rubber or other elastic shoe, is secured to a two part frame 36, the arts of which are held together by a screw bolt 37, which carries the curved guide roller 39 at its lowerend. This roller 88, rests between and moves on'the op osite sides of the roller, and forms a cent a? support for the shoe, while the ends of the latter are supported on the pins 40.

Bearing against the rear face of the shoe at its ends are the flat springs 41, which yieldingly hold the shoe in the path of movement of the knob shanks.

The machine as above described can be used for removing grease or oil from the knobs or other articles or forgrinding, buffing, and burnishing them. For removing grease or oil, scouring brushes like those shown in the drawings are used, and soap, water and pumice stone or other scouring agent is fed onto and against the rapidly revolving brushes through the opcning in shaft 1!). If it is desired to bull orfpolish knobs, cotton wheels are substituted for the bristle brushes shown, and for burnishing, as after dating, the steel or biass wire s ratch bruslics are used. in all of these operations, the knobs are placed on thc'pins' 12 by an attendant located in advancc ol' the brushes and are,,removed by an atftcndant located in rear of the brushes, or one attcudunt may both place vc ihc articles. As the knobs approach the brushes they engage the friction shoe and bear lhcrcaguinst with sullicicnt pins 39 located on by the block 32, j

of sufiicient lat/ pressure to cause the knobs to be rotated as they are moved under the brushes. Asthe forward movement of the knobs iscomparatively slow, and as the brushes make any- I where from six hundred to twelve hundred revolutions a minute, it will be seen that the 1 knobs will be rotated several times during their contact with the brushes, thus bringin all parts of the outer surface of the knob ant its shank into position to e repeatedly acted 1 u pon by the brushes.

l While I have,described the ini movement as a knob scourin polishing and urnishing I machine I would ave it understood that it I is equally applicable for ferrules, escutcheons,

l rings, and a] other circular or cylindrical ar ticles, hence the term knob is intended to include any and all the articles that can be supl ported in a position to be acted upon by either of the two brushes, and be rotated while in contact with the brushes, so as to present its entire outer surface to the action of the brush or brushes.

It is evident that changes in the construc- I tion and relative arrangement of the several parts might be made without avoiding my invention and hence I stood that I do not restrict myself to the particular construction and arrangement of parts shown and described, but,'

Having fully described my invention what I claim as new and desire to secure by Letters Patent is:

I. The combination with a rapidly rotating brush or wheel, of a table having a knob support thereon, the latter ada ted to be moved to car the knob into t e ath'of movement of t e brush or wheel, and means arranged to be en aged by the knob for rotating the same While it is being acted upon by the brush.

2. The combination with a rapidly rotating brush or wheel and a slowly rotating table carrying a series of upwardly projecting knob sup orting pins the latter adapted to carry the nob into position to be acted u on by the brush, of .a stationar yielding s cc for rotating the knobs while t 1e latter are being moved by the table and acted upon by the brush. f

The combination with a hprizontal table having a series of upwardly projecting knob su porting pins, means for rotating said tab e, and a rapidly rotating brush l0- l (rated above the table in a position to succes- 1-0 sively engage the knobs carried by the pins, of a stationary yielding friction shoe arran ed j to engage the knobs while the' latter are e- I ing moved by the table/and acted upon by l the brush.

4. The combination of ,a table having knob carrying means, a rbtatin wheel or I brush comprising two members 1 an anglc to each other and adapted l the top and side of tho/knob, and

to engage means 101' would haveit underisposcd at by the brush, an

causing the knobs to rotate while being acted upon by the brush or wheel.

5,?1? e combination with a revolving bruslifa table having a series of knob carrypins which latter are successively moved into the path of movement of said brush, and means for feeding a scouring or abrading material to the brush, of means for rotating the knobs on their carrying pins, while the knobs are being acted upon by the brush.

6. The combination with a revolving table having a series of knob carryim pins, a revolvin shaft, and a brush carried by said shaft an engaging the top and side of knob on the pins, of means for rotating the knobs on their carrying ins while bein acted upon (i means for feeding a scouring or abrading material to the brush.

7. The combination with a receptac1e, a

revolvin table supported over same and provide with a series of knob supporting pins arranged concentric with the axis ofthe table and a rapidly rotating brush located in a position to successively en age the knobs on the pins of means carried by the receIp tacle and disposed to be engaged by t e knobs for rotating the knobs on their pins while they are being acted u on by the brush.

In testimony whereof, I ave signed" this specification in the presence of two subscribing witnesses.
